They are on the list as "Technical" bulletins for models like the 81 SRX & 83 Vmax but......I cannot find them for the Exciter in which we all know from the 87 butterflies to the roundslides of the 1988-89's had jetting updates and a airbox update. B.T.W. I have a complete O.E.M. Yamaha jetting update kit in the package if this can help ?

I helping a friend out with his wifes Exciter 570-I ( 1989 ).
And my "old" memory ( 39 years
) tells me that way way way back I have read about a Service bulletin / Jetting update for the ones that have the heated Mikuni VM-38 carbs.Sorry to say... but it would probably not be economical to ship your excellent jetting update kit over the pod to SWEDEN
I would really apriciated If you could tell me what the jetting update consists of and the airbox update !!!
Please help me out !
